Internal combustion engines are mostly found in cars and trucks require an electric motor to start. Starter motor aims to rotate the engine until the internal combustion process can be taken over. Because the electric motor is often takes several hundred amperage to operate, it is necessary to isolate the circuit of the ignition key from the ignition. This is one of the main reasons to use the starter solenoid.
It is the solenoid electrical components consisting of metal slug with the coil around it. When the coils receive electric, the resulting magnetic field and core are forced to move. This Act was used in the starter solenoid to act as some sort of relay.
This solenoid is usually connected to battery voltage on one side and the starter motor on the other side, and is activated by a switch. When the switch is turned off, the solenoid acts to provide battery voltage directly to the starter.
When the starter solenoid is installed directly on the motor starter, they often perform other useful actions. Linear solenoid core movements can be used to move the teeth of the starter, cause it to act as the flywheel.
If the starter solenoid is not installed directly on the motor, then other methods need to be used to perform this action. Generally involves separate solenoid, starter gear shaft will have a helical groove. This causes a rotational movement of the starter shaft to force the teeth into place instead of a linear movement of the solenoid.
In the application of separate solenoid, they are usually easy to be replaced. This solenoid is usually mounted somewhere in the engine compartment, and usually has four electrical connections. Integrated solenoid Starter is usually more difficult to reach the start, and when it failed generally need replacing or constructing the back the entire starter.
In this case it is necessary to remove the battery before attempting to operate the solenoid, as they have an electric current which can easily occur during korsleting operations improvement.
